WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement descriptionField = wait.Until(ExpectedConditions.ElementIsVisible(By.Name("description")));

If the element is still not found, double-check the page's HTML to confirm that the description field exists and that its name attribute is correctly specified.
